TRANSPORTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 615,043, dated November29, 1898. Application filed December 7, 1896. fierial No. 614,781. (Nomodel.)

To aZZ whom it may concern: Be it known that I, FRANK SAMUEL Pnrr, asubject of the Queen of Great Britain and Ireland, residing at 3Blenheim Square, Dover, 5 in the county of Kent, England, have inventedcertain new and useful Improvements in Transporting Apparatus; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will I0 enable others skilled in the art towhich it appertains to make and use the same.

This invention for improvements in transporting apparatus has for itsobject to facilitate the transportation or loading or unloading ofcargo; and it consists of a beam or girder adapted to be fixed orsupported in the required position to transfer the cargo, a carriageadapted to travel along and be guided by the beam two sprocket-wheels,with a ratchet-wheel bolted securely onto the side of eachsprocket-wheel, mounted on the carriage, two chains passing over thesprocketwheels and along the beam in reverse directions, ratchetmechanism adapted when in 2 5 gear to prevent the sprocket-wheelsturning in a direction to lower the chains, and a means for moving theratchet out of gear when desired.

When the apparatus is used to transfer a load from the outer end of thebeam to the inner, the chain passing to the outer end is hauled on untilthe block comes in contact with the carriage. The carriage is thenpulled by this chain to the outer end of the beam 3 5 and is securedfrom inward movement by belaying or fastening this chain. The other orhauling chain is then hooked onto the load and hove up, and when theload is at the desired height the belaying-chain is unfastened, the

continued hauling on the chain then traversing the carriage and its loadalong the beam, the ratchet mechanism preventing the load from loweringduring this traverse. \Vhen the load arrives at the required place, thecarriage is prevented from further inward movement by coming against astop or by fastening the belaying-chain, the ratchet is drawn out ofgear by a rope or automatically by a projection on the beam, and thehauling-chain is slackened to lower the load.

When the apparatus is used to transfer a load from the inner end to theouter end, the functions of the chains are reversed, the chain passingto the inner end now becoming the belaying-chain and the chain passingto the outer end the hauling-chain.

By this apparatus the load can thus be transferred inward or outward atpleasure without altering the chains.

In the accompanying sheets of drawings, Figure 1 is an elevation of anapparatus with one cheek of the carriage and the ratchet and its leverfor working the inside ratchet-wheel removed arranged for outwardtransportation and constructed according to this invention, showing theposition of the parts as the load is being raised and in dotted linesthe position when being transported; and Fig.2 is a similar viewarranged for inward transportation showing the two ratchets and theirlevers 7o thrown out of gear. Fig. 3 is a plan of Fig.

2. Fig. 4 is a sectional elevation of the transporting-carriage with onecheck of the carriage and the ratchet and its lever for working theinside ratchet-wheel removed, the dotted ratchet and the lever showingthe position when in gear and the full-lines ratchet and its levershowing the position when tripped ready for hoisting a load; and Fig. 5a sectional end view of the same. Fig. 6 is a similar view to Fig. 4,showing a slight modification. Fig. 7 is a view showing a modificationof the apparatus arranged for transporting cargo in the hold of avessel.

The beam ct is suspended by span b from the ships mast by means of atackle or other suitable support and is stayed by means of ropes at itsends to other fixtures. As shown, the beam is double, so that loading orunloading operations can be conducted at either or at both ends and is.L-shaped incross-section.

The carriage 0 works underneath the beam to and is provided with sidecheeks, carrying rollers 61 running on the top surface of the head orflanges of the beam or girder, so that 5 the carriage is free to runfrom end to end of the beam.

Two sprocket-wheels e e are mounted on the carriage 0 below the beam,and the inner sprocket-wheel e is provided with a ratchet wheel f andratchet g, preventing when in gear its rotation in a forward direction,and the outer sheave e is provided with a ratchetwheel f and ratchet g,preventing when in gear its rotation in the backward direction.

In order to throw the ratchets g g out of gear with their ratchet-wheelsf f automatically at the desired parts of the beam, the beam to isprovided on its under side at the said parts with projections 71/ j, andwhen the carriage is traversed on and over them the projections come incontact with either of the tails t' t" on the ratchets or the separatelevers ZZ, acting on the ratchets, and throws the ratchets out of gear.The ratchet-wheel g is shown in Fig. 1 in gear with its ratchet-wheel fin dotted lines and forced out of gear by the projection 7i, acting onthe lever Z, in full lines, and Fig. 2 shows the projection j acting onthe ratchets and levers throwing the ratchets g 9 out of gear with theirratchetwheels. Thus at both ends of the traverse both ratchets arethrown out of gear with their ratchet wheels, and the sprocketwheels arefree to revolve in either direction. Springs 0' s r s tend to put theratchets in gear with their ratchet-wheels.

Chains m m are passed over the sprocketwheels 6 e, thence overguide-pulleys n 71/ on the beam, so that the chains are practicallyparallel with the beam, and thence over suitable guide-pulleys 0 to anydesired spot for manipulation. The chains m m are provided with blocks2) p, that come in contact with the carriage-frame and prevent thechains from being hauled in any farther.

The operation is as follows: The carriagec is hauled inward by means ofthe chain m to the position shown in Fig. 1, the block 12 coming incontact with the carriage c and fixing the chain m with reference to thecarriage c and the chain m being paid out as required. In this positionthe ratchet gis thrown out of gear with its ratchet-wheel f by theprojection 71, acting on the lever Z, that forces the ratchet out ofgear, and the chain on is lowered to receive the load. The load is thenhauled up by the chain m, and when the load is at the desired height thechain m is released, so that the pull on the chain on traverses the loadoutward along the beam. Immediately the lever Z leaves the projection hthe ratchet 9 falls into gear with its ratchetwheel and prevents theload from lowering, but it can be raised still farther, if desired, byholding on to the chain m. At the outer end of the beam the carriage 0comes against the stops t, and the projection j, acting on the tail t'ofthe ratchet g, raises the ratchet out of gear with the ratchet-wheel, sothat the load can be lowered. By this arrangement it is not necessary topay out the belaying-chain at the same speed as the hauling-chain, thebelaying-chain being used only to fix the carriage at the desired spot.

It will readily be understood that when desired to traverse the loadinward the chain m becomes the hauling-chain,while the chain m is thebelaying-chain, as shown in Fig. 1, the ratchet g then acting on itsratchet-wheel f, as previously described for the ratchet g andratchet-wheel f.

In the modification shown in Fig. 6 the ratchet-wheel and ratchet arereplaced by the drum or brake surfaces 12 c and straps or bands 10 w andlevers w 00', and in this arran gement the brake is applied by theprojection 1 when traversing outward to the drum t and when traversinginward to the drum 1), the projection g extending the whole distance ofthe traverse. At places where it is necessary to lower, the projection yis removed to enable the brake-levers to release themselves.

Fig. 7 shows thebeam a supported from the deck-beams 1 by means of thehangers 2. The arrangement is suitable for transferring cargo from anypart of the ships hold to under the hatchway 8, and in this case thelevers Z Z are dispensed with.

It will readily be understood that the apparatus may be employed inwarehouses or on other places where it is desired to handle goods orcargo for loading or unloading purposes or for storage.

Instead of operating the ratchets automatically they may be attached toa rope, by which they can be pulled out of gear at any desired place, sothat the load can be deposited at any part of the length of the beam,and the ratchets may be dispensed with altogether and kept out of gearby a pin inserted in the holes 4 across the carriage, as shown in Fig.4c. This, however, is only done when landing cargo on deck and whentraverse is not necessary.

'What I claim, and desire to secure by Letters Patent, is

A load-transportin g or loading and unload ing apparatus, consisting ofa beam, a carriage running on the beam, of two sprocketwheels mounted inthe carriage and of two chains passing from the sprocket-wheels alongthe beam in opposite directions, ratchet or brake arrangements toprevent the rotation of the sprocket-wheels in adirection to lower theload and means of throwing the ratchets or brakes out of gearautomatically or otherwise so that loads can be transferred in eitherdirection without unreaving the chains.

In testimony whereof I have affixed my signature in presence of twowitnesses.
